Check-indorsing machine



- 1930- L. J. ZAHN CHECK INDORSING MAOHliNE Filed July 13, 192 8INVENTOR LAWRENCE J. ZAHN 9 the junctionpoint of the arms 36 and 37, and

associated with it is an adjusting nut 40, threaded as shown in Figure4. The stud 38 is providedwith a notch 41 which is adapt ed to engagethe head of the 'nut 40 as shown in Figure 4,' 'anda 'spring-42eis usedto return the carrier frame to its normal-position on releasing the nut40 from the notch 41.

WVhen pressure is applied "to the. adjusting nut 40, "cewar'dthe.,rrfiiaitni'egraisee the in} 1 .ner end of th carrier'frame,' se"thatthearms 18 and 19 will take the position indi cated by the'dotted line 43(see'-'Fig. 2),

thereby lifting the diegstructure afrom 611- gagement with the driveroller, and the die plate can. be then re no'ved for-the {purpose of adjus'ting the die blo'ck'tofget suitable in diciaforthecheckstampingoperation.

* On oneend er the shaft 44, of the die struc ture-is slidably mountedby e keynot shown,

a clutch element 46; The clutch elementj46 engages within theclutchhousing a clutch plate of any suitable *materi'alfsuch as cork orcomposition thereof, which in turn en' gages a clutch roller 48.carriedon a suitable bearing. The clutching effort is regii lated by aspring 49, and adjusting nuts 50,

and the'surface of theclutch roller 48 'is' adapted to engage thefriction surfaceforme'di bythe' parts 9 and 10 ofthe driverollerf -7,gthe rubber portion ofthis part of the drive roller being adapted toprovide, friction and the fabric portion to resist wear; and Ihave foundthat the combination of two suoh, ma-

terials gives the best results in a machine of this characterl i eV..Onfthe, opposite endof the-die structure from the; drive roller 48is" carried a trip: fmechanism" 51 generally ofthe same'type,

as disclosed in Jahn'Patent 856,345, issued Junell, 1907. The lever52 ofthe trip mechanismis adapted to'be engagedby the checks as they passbythe driveroller 7=andthe die structure '24, thereby allowing the clutchstructure 24 through the' medium of the I clutch justdescribed to turnthe ,die struc-e v ture, and-plate so the desired inscriptio'njma'y bestamped on the check as itp'ass'e's'between the drive roller and thedie;1 v a H I In order toproperly actuate the-trip mechanism and to pass thechecks betweenthe drive roller andthefdie, a pair of trip guide rollers25 and 26 are provided. The trip tongueis engaged. byfthat part of thecheck spaced between these guide rollers; also a plurality of fingers53'are'provided, Atleastone Jpair'of these fingers have their ends extending downward into the] check receiving compartment 54, As'shown inFigure 2,; one pair of the fingers 53jare positioned ."within the slots14 and 15 in the drive roller, aspre viously referred to'and assopositioned, are slightly below the peripherylofthe drive'roller, as willbe seen from Figure2; A guide plate 55 my be attached to bottom" of the1 7 3 990 up i ii -e1. .1

carrier frame toassist in guiding the checks to the-compartment 54. Asshown in Figure .2 this comprises a member 56, which has serrations 57;'As the checks pass between the drive rollerand the die, the incomingedge thereof is thrownrxforward into; engagement Withoneof theserrations 57, thereby slightly retarding,- for a brief interval, thisedge of the check, allowing the'leavingedge'to dropjdownwarrttbwardiftnefbottbirror the compartment,as'indicated"by the dotted lines58. have@fo'undthat without this special means that the checks are quiteapt to strikev against the; outer zwagll of the compartment and stickthere in a sidewise position, but the. means just de'scribed absolutelyeliminates tliisdifiic'ulty-Q e v v a T As a furtheraid in insuring thatthechecks are properly stacked in "the compartmentb l, I have providedthe eccentric mounting of the carrier f-rame ontheisha'ft 20,as'pr'e'vious' ly described, and by means of pins -inserte'd' in theholes 59,-the rod 20'can be turned and on account of the eccentricposition'of'thefixed pin 21, thecarrier" frame is movedso that the diestructure is moved ashort-distance, ereuetely around thedrive roller-7-,

thereby changing} the angl'e at which the checks enter-the compartment54; 1

' The combination "of these two special rangements gives aghighlysatisfactory result. Supported'jon the carrier frame isan 'a'uxiliaryframe 60, h'aVi'ng side plates 61 and 62.

This auxiliaryfranie' carries a felt roller 63, anink roller :64, and awiper roller 65. The felt or ink absorbent roller 63 has its bearingends *ca'rriedfibya slot-80 infle'ach of the side 7 e e plates 61 and62, and is resiliently held-in position by the springs 66'and 67,inengagement withtheinkr'oller 64, which in turn is positioned sees tocarry ink-from the bottom of the auxiliary frame to the ink'absorbentroller*63.- The amount of ink which the ink roller-64 will carry to theroller 63 -isregulated by the wip'erjroller': 65, 'which latter rollerhas its ends positioned ingrooves '68, in

the plates 61 and 2; Tile roller 65'is held in} positionin the groove 68by meansof-a' pair of roller bushings each having flanges 69 and 70between which flanges, rests a spring -7 1, thetension of which can beadjusted by a screw 72, so as to 'g'ivethe' desired 'pressure offth ewiper roller 65 ontheink roller64. A spring pawl'73 and a ratchet 7rontheinkyreuer '64 is provided to prevent the ink'roller from beingturned in reverse direction, which would are carried ona back plate 78.,
